A few weeks after I was diagnosed with severe mononucleosis, I was referred to him for follow-up treatment. He perscribed "45 minutes of strenuous exercise--work up a sweat". I tried to tell him that I was "bone-deep" exhausted, as in too tired to get out of bed, too tired to eat, etc. He insinuated that I was just lazy and to go back to work and forget about it. I found a doctor that was familiar with the symptoms of chronic fatigue and was told and read in my research that Dennen's instructions were the worst possible thing I could have done and it caused this condition to be permanent. He ruined my life. He has since moved from Dushore and I have been unable to learn his whereabouts.
